1. Push ups, Chin ups, Dips, Crunches, and weight workouts.
2. Heavy Bag

How many times a week should i do these and what things should i do on the same days?

20
10
5
15

If u r a new comer den so

Now this is just what i was told, and my exp. punching with weights does not improve much as it really only puts more stress on the joints. Try 16oz gloves if you want to get faster, or hitting a tire with a sledge if you want to build power.

When throwing a left hook should your thumb side of your fist be towards you or up?
